Description
Concrete CMS Community Store before 2.7.8 renders customer-supplied order fields without HTML escaping in checkout and admin views. Unauthenticated attackers can store script payloads in billing name, email, or phone fields that execute in authenticated manager sessions to create rogue accounts or exfiltrate data.
